In my feature breakdown tree, how come some stories have the ability to add task cards directly from the tree view? i.e. some Story cards have the ”+” link on the bottom of the box.

Hello DEng – When you configure your feature-breakdown-tree, all cards of type other than the last type as specified in the configuration will show the (+) in the tree. This is because, as specified in the tree configuration, the last card type cannot have any children.

If you are referring to the Feature breakdown tree in the standard “Agile Hybrid Template” that ships with Mingle, as per the configuration, cards of type Feature can have children of type Story. Cards of type story cannot have any children.

Hope that clarifies things.
